The link brings you to a dead page at the Google Play store, and no one has reported actually testing out the app.

We've reached out to Facebook and Instagram for comment and will update if they fess up.

If this incident seems familiar, it's because this is very similar to what happened when Facebook launched its Snapchat competitor, Slingshot; someone posted the app page on the iTunes store before it was actually available. If this is, in fact, exactly like Slingshot, maybe Bolt will appear in the next few days. Now we just have to wait and see if it's actually a worthy competitor, or if it ends up being another needlessly complicated knockoff, like Slingshot. [The Verge]
